Which batteries to use in MXDL host?

[50Freestyle]

I'm not for sured which 3.6V CR123A batteries on DX would work in the 5W CR123A powered MXDL host? Can I use unprotected cells (http://www.dealextreme.com/details.dx/sku.722) or would I be risking my diode by doing that? There are protected cells (http://www.dealextreme.com/details.dx/sku.3273) but I am worried they will not fit in the host. Any reccomendations are greatly appreciated.

Thanks,

get both. ask questions later. the unprotected is only 3 bucks more anyways.

I am asking the question so I don't have to buy both . I just want to know if anyone has ever had problems with unprotected cells and if anyone has had problems fitting those protected cells into the host.
